Select the option that contains only computer input devices.

Joystick, keyboard, mouse and digitiser are all input devices that feed data or commands into the computer.

A digitiser or graphics tablet turns hand-drawn strokes into digital coordinates the computer can use.

The set with a printer fails because a printer is an output device that produces printed pages.

The set with a monitor alongside mouse and joystick fails because a monitor is an output display device.

The set pairing a digitiser with a monitor again includes the monitor, which outputs rather than inputs.

Input devices send information in, output devices send results out, and this is the basic test to sort them.
